People have been taking the antinatalism view for decades, if not centuries. And yet, things keep getting better. The future has a positive bias. I know that some will disagree with my position on this, but instead of looking at whatever is the horror du jour, consider the broad sweep of history. Do you really want to live in the 1100's? The 1840's? The 1950's? If I had a time machine, I'd head straight for the future. Until aging is cured, the only way to live on is through your germline.
Don't forget that humans are just another species of mammal. Evolution has provided us with a powerful drive to procreate. Later, when you're the parent of a surly teenager like I am, you might find yourself questioning your procreational decisions, but evolution doesn't care about that. It's interesting that as cultures get more wealthy, educated, and secure, the birthrate slows down, and has dropped below the replacement rate in some developed nations.
